Development History
SMART (System-integrated Modular Advanced ReacTor) is an integral-type small reactor, developed by KAERI (Korea Atomic Energy Research Institute) after 19 years of research since 1997. It received the first-ever Standard Design Approval (SDA) from Korean regulatory body for a 100 MWe (330 MWt) integral reactor in 2012.
SMART generates only a tenth of a large nuclear plant (over 1,000 MWe), but since it is an integral-type reactor, it has enhanced the inherent safety by containing major components such as pressurizer, steam generator, and reactor coolant pumps in a single reactor pressure vessel. It was designed especially for export and can supply a city with a population of 100,000 with 90 MW electricity and 40,000 tons of fresh water per day concurrently.
Described below is the brief history of the SMART development.
